I gave up on beds in crates long ago. Now I buy thick fleece blankets and they do rip them a bit but they are still useable. My boys are adults though. When they were pups my red boy made a few beds explode.

These blankets are from Walmart and were recommended by my breeder. $5 for a twin blanket and they are surprisingly comfy.
If your girl is eating the beds/blankies as she shreads that's a different issue and I'd be hesitant to use anything.
